A Multi-Level Modeling Language
ML2 is a textual modeling language for multi-level conceptual models, i.e., those in which classes can also be subject to categorization, extending beyond the two-level divide between classes and their instances.
The language was designed using as a basis the MLT* multi-level modeling theory. As a result, it embodies many rules to ensure models are sound.
The language was originally introduced and described in Claudenir M. Fonseca’s M.Sc. thesis.
A paper presenting ML2 received the best student paper award at ER 2018:
